Abstract:
PROBLEM TO BE SOLVED: To aggressively and commercially use properties of an explosively propagating medium as advertisement business. SOLUTION: An advertisement distribution system is provided with a contents provision side system 30 which adds a contents ID as an identifier to each contents to provide contents for a user terminal 50, the user terminal 50 which acquires contents from the contents provision side system 30 through a network and recognizes the contents ID added to the acquired contents to send in onto the network, a sponsor side system 70 which distributes a prescribed advertisement to the user terminal 50 through the network on the basis of the contents ID to be sent, and a proxy server side system 10 which manages the contents ID added to contents and sends a trigger of advertisement distribution to the sponsor system side 70 which distributes and advertisement on the basis of the contents ID.
Abstract:
PROBLEM TO BE SOLVED: To detect the presence or absence and kind of processing performed to contents while discriminating the kind by combining plural kinds of digital watermarks. SOLUTION: This system is provided with an embedding device for adding a prescribed additional signal to the contents data of digital contents and a detector for detecting the additional signal from the digital contents. The embedding device is provided with a watermark designing part 110 and embedment signal generating parts 121-123 for generating plural kinds of mutually related additional signals whose resistance to the processing of the digital contents is different and a synthesizing part 130 for adding the plural kinds of additional signals to the contents data. Also, the detector for detecting the additional signal embedded by the embedding device is provided with an individual detecting part for individually detecting the plural kinds of additional signals from the contents data and a judging part for judging the kind of processing performed on the contents data by checking the level of the deterioration of the additional signal based on the detected result of the individual detecting part.

PROBLEM TO BE SOLVED: To acquire a dependence relation between service processes, and to efficiently and safely execute the service processes. SOLUTION: This computer system includes: a discovery part for detecting information about constitutive elements; a repository for holding a prescribed attribute of each constitutive element and a set of data indicating a relation between the constitutive element and the other constitutive element; a correlating part for correlating a service constitutive element with a corresponding action-objective one constitutive element; and a determination part for determining whether an action corresponding to the second service constitutive element is permitted to be executed or not, when the action corresponding to the second service constitutive element is requested during execution of an action corresponding to the first service constitutive element, and when the at least one constitutive element that is an object of the action corresponding to the second service constitutive element is included in the constitutive element that is an object of the action corresponding to the first service constitutive element.

Abstract:
PROBLEM TO BE SOLVED: To provide a practicable and robust method and a system of digital watermark. SOLUTION: The digital watermark system consists in embedding additional information in digital data. One frame is composed of N samples fetched from the digital data and the following frame is determined, in such a way that it overlaps with the foregoing frame by M(0
Abstract:
PROBLEM TO BE SOLVED: To provide an electronic watermark system which makes erasing of a visible mark and embedding of an invisible mark inseparable in the case of erasing a visible mark and embedding an invisible mark. SOLUTION: In the case of erasing a visible mark and embedding an invisible mark (84), by not sequentially erasing the visible mark and embedding the invisible mark but performing the erasing of the visible mark and the embedding of the invisible mark at the same time, it makes difficult to obtain an original image data in which the visible mark or the invisible mark is not embedded even if a snap shot of a memory is taken during processing. Moreover, in the case of erasing the visible mark and embedding the invisible mark (64), the invisible mark is embedded in an area in which the visible mark was embedded. Therefore, it becomes difficult to presume the newly embedded invisible mark, even if the images before and after the erasing of the visible mark are compared with each other.
Abstract:
PROBLEM TO BE SOLVED: To suppress the degradation in picture quality or the like of media information subjected to padding processing by properly certifying who is a true owner and adaptively determining the manipulated variable for characteristic values such as picture element values. SOLUTION: In a data hiding method which pads media data with message data, a key having a prescribed value is taken as input of a specific function to obtain a secondary key. Based on this obtained secondary key, the padding position of message data is specified, and a function for padding to be used in this specified position out of plural functions for padding is specified. The padding processing of message data is performed in the specified position based on the specified function for padding.
Abstract:
PROBLEM TO BE SOLVED: To appropriately secure a resource for executing designation processing designated by a user. SOLUTION: The resource management device for managing resources for executing processing within a computer system includes: a resource securing part which secures the resource for executing designation processing designated by the user; a query part which queries the user for whether to perform additional securing of resource when the designation processing cannot be completed within a secured time with the secured resource; a restart instruction part which causes the resource securing part to secure a resource in response to receipt of an instruction for additional securing of resource from the user, and to perform the continuation of the designation processing on the secured resource.

Abstract:
PROBLEM TO BE SOLVED: To provide a method and a system for directly operating information in compressed digital audio data. SOLUTION: A system which embeds additional information in compressed audio data has (1) a means for restoring a MDCT(modified Discrete Cosine Transform) coefficient from the compressed audio data, (2) a means which finds frequency components of the audio data by using the restored MDCT coefficient, (3) a means for embedding the additional information in the found frequency components in a frequency space, and (5) a means for generating compressed audio data from the MDCT coefficient embedded in the additional information.
Abstract:
PROBLEM TO BE SOLVED: To detect reliably the processing to the audio data while burying so as not to detect a change of tone quality due to burying of additional information with human auditory sense by burying the additional information in a changeable range of a frequency that the audio data are buried. SOLUTION: A frequency conversion block 120 calculates a frequency component of an audio signal. An auditory sense psychology model calculation block 130 calculates an area hard to differentiate the change based on a characteristic of a human ear. An additional information burying mask generation block 170 generates a mask used when the additional information is buried. An additional information burying block 140 buries the inaudible additional information in the audio signal. That is, the block 140 adds a signal/time companding/ detecting synchronizing signal to the frequency converted audio signal in the mask direction in an inaudible range based on the calculated auditory sense model. A frequency inverse conversion block 190 inversely converts the frequency converted audio signal.
